Abstract

The present disclosure relates to an emissive construct, which can be used in various OLED applications, for example, top-emission white organic light-emitting diodes. The emissive construct includes a fluorescent emissive layer, a partial hole-blocking layer, and a phosphorescent emissive. A recombination zone is shared between the fluorescent emissive layer and the phosphorescent emissive layer, such that the thickness of the partial hole-blocking layer is less than about one-third of the thickness of the recombination zone.
